I have an AMD A4-6300 CPU with an integrated Radeon HD 8370D GPU and I'm trying to get OpenCL to work with the GPU. To use OpenCL, I installed the latest Catalyst drivers from Vi0l0's repository. The graphics seem to be working fine, but the clinfo command doesn't seem to detect the GPU.
Here are some of the pacakages I've installed:
amdapp-aparapi 20130123-1
amdapp-codexl 2.3.605-1
amdapp-sdk 3.0-22
amdapp-sdk-docs 3.0-22
catalyst-control-old 15.9-4
catalyst-hook 15.12-10
catalyst-libgl 15.12-5
catalyst-utils 15.12-3
opencl-catalyst 15.12-6
xorg-server 1.17.4-2Here's the output from fglrxinfo which seems to detect the GPU:

How can I get clinfo to start detecting the GPU? Do you have any pointers about how I should I go about debugging this?
Thanks

from https://wiki.archlinux.org/index.php/GPGPU#AMD.2FATI
sdkAUR: AMD CPU runtime
If I understand correctly, this is only the the runtime for the CPU. For the GPU you probably need one of these:
opencl-amdAUR: proprietary standalone runtime for AMDGPU
amdgpu-pro-openclAUR: proprietary runtime for AMDGPU PRO
opencl-catalystAUR: AMD proprietary runtime, soon to be deprecated in favor of AMDGPU

Richland's APUs have TeraScale based gpus, whose CL support was dropped in 15.11 when they switched to a newer APP platform (1912.5)
You should use 15.9 (1800.11), which as of now can be found in either catalyst-total or standalone opencl-catalyst
